如何生成行数多于列数的随机矩阵？例如，行数是列数的倍数，例如10 columns 500 rows或20 columns 1000 rows等。

您可以使用诸如RAND (http://www.mathworks.com/help/techdoc/ref/rand.html)和RANDI之 (http://www.mathworks.com/help/techdoc/ref/randi.html)类的功能来做这些事情。例如：
nCols = randi([10 20]); %# A random integer between 10 and 20 nRows = nCols*50; %# Number of rows is a multiple of number of columns mat = rand(nRows,nCols); %# A matrix of random values between 0 and 1
